Intel Core i5-14401TE vs Intel Core Ultra 7 266V Comparison

Intel Core i5-14401TE and Intel Core Ultra 7 266V are both current production parts, but they target different segments of the market. The i5-14401TE is a desktop processor built on the Raptor Lake architecture, while the Ultra 7 266V is a mobile processor using the newer Lunar Lake design. The database contains a full benchmark profile for the Ultra 7 266V, but no recorded benchmark scores for the i5-14401TE, which makes a direct numerical comparison lopsided. However, the available data for the Ultra 7 266V provides a clear picture of its performance tier, and the architectural specifications of the i5-14401TE allow for a qualitative analysis.

Head-to-Head Benchmarks

The benchmark database includes no recorded scores for the Intel Core i5-14401TE, so head-to-head comparison is not possible with numerical data. The i5-14401TE has an average benchmark score of zero and no entries in its benchmark array. In contrast, the Intel Core Ultra 7 266V has a comprehensive set of measurements across Cinebench and Passmark tests.

The Ultra 7 266V posts a Cinebench R23 multi-core score of 16544 and a single-core score of 2335. In Cinebench R20, it scores 6948 multi-core and 980 single-core. The Cinebench R15 results show 1667 multi-core and 235 single-core. These scores indicate a strong mobile processor, and the database places it in the 76th percentile of all CPUs, with an average benchmark score of 23297.

Passmark results for the Ultra 7 266V show a multi-thread score of 19461 and a single-thread score of 3943. The data compression test records 187050, while data encryption scores 13822. Integer math scores 41558, and floating point math scores 56923. The extended instructions test records 15928, and the physics test scores 1608. Prime number finding scores 191, and random string sorting scores 22905.

The nearest rivals for the Ultra 7 266V in the database are the AMD Ryzen 7 5800H, Intel Core i9-11900F, Intel Core Ultra 9 288V, and AMD EPYC 4124P. The Ultra 7 266V leads the Ryzen 7 5800H by 0.1 percent, the Core i9-11900F by 0.2 percent, the Core Ultra 9 288V by 0.3 percent, and the EPYC 4124P by 0.6 percent. These are very small margins, indicating the Ultra 7 266V sits at the top of a tightly clustered performance group. Since the i5-14401TE has no scores, any claim about its performance relative to the Ultra 7 266V would be unsupported by the recorded data.

Architecture Differences

The two processors come from different architectural generations and manufacturing processes. The Intel Core i5-14401TE uses the Raptor Lake architecture, specifically the Raptor Lake-R refresh, built on a 10 nm process at Intel's own foundry. The Intel Core Ultra 7 266V uses the Lunar Lake architecture, built on a 3 nm process at TSMC.

The core configurations differ significantly. The i5-14401TE has 6 cores and 12 threads, supporting simultaneous multithreading. The Ultra 7 266V has 8 cores and 8 threads, with no hyperthreading. Base clocks are 2.00 GHz for the i5-14401TE and 2.20 GHz for the Ultra 7 266V. Boost clocks are 4.50 GHz and 5.00 GHz respectively.

Cache hierarchies are structured differently. The i5-14401TE has 80 KB of L1 cache per core, 1.25 MB of L2 cache per core, and 20 MB of shared L3 cache. The Ultra 7 266V has 192 KB of L1 cache per core, 2.5 MB of L2 cache per core, and 12 MB of shared L3 cache. The i5-14401TE has a larger total L3 cache, but the Ultra 7 266V has substantially more L1 and L2 cache per core.

The i5-14401TE supports DDR4 and DDR5 memory over a dual-channel bus, while the Ultra 7 266V supports LPDDR5X memory, also dual-channel, with a recorded memory bandwidth of 136.5 GB/s. The i5-14401TE supports ECC memory, while the Ultra 7 266V does not.

PCIe connectivity differs. The i5-14401TE provides Gen 5 with 16 lanes from the CPU, while the Ultra 7 266V provides Gen 5 with 4 lanes. Integrated graphics are also different: the i5-14401TE uses UHD Graphics 730, and the Ultra 7 266V uses Arc 140V.

The physical packages are distinct. The i5-14401TE fits Intel Socket 1700, a desktop socket, and has a die size of 215 mm². The Ultra 7 266V uses Intel BGA 2833, a mobile package, with no die size recorded. Thermal design power differs sharply: the i5-14401TE is rated at 45 watts, while the Ultra 7 266V is rated at 17 watts. Release dates are close, with the i5-14401TE launching in June 2024 and the Ultra 7 266V in September 2024.

Where Each One Wins

The data shows distinct strengths for each processor based on their design goals.

The Intel Core i5-14401TE wins on connectivity and memory flexibility. It offers 16 PCIe Gen 5 lanes from the CPU, which supports high-bandwidth expansion cards such as graphics cards and NVMe storage. Its memory controller handles both DDR4 and DDR5, giving builders a choice of memory technology. The inclusion of ECC memory support makes it suitable for error-sensitive workloads. The 45 watt TDP is higher, but it is still a power-conscious desktop part, and the larger 20 MB L3 cache could benefit workloads that repeatedly access a large working set.

The Intel Core Ultra 7 266V wins on power efficiency and single-thread capability. The 17 watt TDP is less than half of the i5-14401TE's rating, which is a major advantage for thin-and-light laptops. The 5.00 GHz boost clock is higher, and the recorded single-core scores are strong: 2335 in Cinebench R23 and 3943 in Passmark. The larger L1 and L2 caches per core (192 KB and 2.5 MB respectively) can reduce memory latency for frequently used data. The integrated Arc 140V graphics is a more capable GPU than UHD Graphics 730, which helps in media tasks and light gaming without a discrete GPU.

The benchmark percentile for the Ultra 7 266V is 76, which places it above most CPUs in the database. The i5-14401TE has a percentile of 50, but this is based on zero benchmark scores, so it does not reflect actual performance. The Ultra 7 266V's measured scores in Cinebench R23 multi-core (16544) and Passmark multi-thread (19461) show it can handle demanding multi-threaded workloads despite its low TDP, likely due to its efficient 3 nm process and high boost clocks.

The Verdict

The data indicates a clear split in purpose. The Intel Core i5-14401TE is a desktop processor built for systems where socket compatibility, memory choice, and expansion capability matter. Its support for DDR4 and DDR5, 16 PCIe Gen 5 lanes, and ECC memory makes it a flexible option for a desktop build, particularly one that needs error-correcting memory or multiple high-speed expansion cards.

The Intel Core Ultra 7 266V is a mobile processor optimized for efficiency and compactness. Its 17 watt TDP and 3 nm process make it suitable for thin laptops, and the recorded benchmark scores show it performs competitively with older high-end desktop parts. The 76th percentile ranking and the narrow leads over rivals like the AMD Ryzen 7 5800H and Intel Core i9-11900F confirm its position as a capable all-around mobile chip.

For a desktop user with an existing LGA 1700 motherboard, the i5-14401TE is the logical choice because of its socket and memory flexibility. For a laptop buyer seeking a balanced processor with strong single-core performance and low power draw, the Ultra 7 266V is the data-backed option. The lack of benchmark scores for the i5-14401TE means the database cannot confirm its performance level, so any purchase decision for that part must rely on its specifications alone.
